specification.

This invention relates to railway rail an-' chors which are employed to prevent longitudinal movements of track rails; and its object is the perfecting of devices of this character to render the same more efiicient in use, more readily applied or disconnected, and less liable to become accidentally disengaged than are other rail-anchoring appliances known to me.

The invention consists in the novel construction, adaptation and. combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an end elevation of my improved rail. anchor applied to a rail which is shown in transverse section. Fig. 2 is a longitudinal section through 2-2 of Fig. 1. Fig. 3 is a horizontal sectional view of the device shown detached, said section being taken substantially on the broken line 3-3 of Fig. 2. Fi 4 is a detached perspective view of a bloc element of the device.

The reference numeral 5 indicates a body having an arm- 6 extending downwardly from one of its ends and may be manufactured by forging or otherwise. This body is provided at its top with a longitudinal slot which opens into a chamber 7, said slot being disposed to aiford a relatively narrow flange 8 at one side and a wider flange 9 at the other side in order that, by tilting as indicated by broken lines a: in Fig. 1, the device may be coupled with the flanges F of a track rail R. After being thus engaged, the device is moved into the upright position in which it is illustrated by full lines in the views, to introduce said rail flanges between the side wall 10 of said chamber and a shoulder 11 provided intermediate the width of the wide flange 9. The floor 12 of said chamber slopes, as shown in Fig. 2, with respect to the underside of the track rail.

13 represents a frame adapted to be inserted into the recess or chamber 7 from the rear end of the device and is provided with an aperture 14 to accomm ate a transversely disposed roller 15, which is preferably fluted.

The body 5 is applied to a rail, as explained, and then advanced to have the arm 6 abut against a track-tie T. The frame 13 containing the roller is then introduced into the body chamber and on being forced forward will cause the roller to be wedged between the underside of the track-rail and the floor 12 of the device to thereby secure the same to the rail and in juxtaposition with the tie T.

To facilitate the engagement or disengagement of the roller with respect to the track-rail and the body, a tapering key may be advantageously utilized, for which end slots 16 are'provided in the side walls of the body and a transverse slot 17 provided in said frame.

To advance the roller, the referred to key is inserted, as indicated by broken lines 18? in Fig. 3, through the slots of the body and frame and when driven in will act against slot faces 16 and 17 to efiect the setting forward of the frame and roller which is carried thereby. To retract the roller, the key is driven into the device, as indicated by broken lines 18 in the view, through the body slots 16 and against the ends 16 Vance end 13 of the frame. 7

The front surface 6 of the arm 6 is aran ed in such angular relation to the under sur aces of the body flanges 8 and 9 that when the latter are seated on the rail flanges F and the arm 6 is brought against the tie T, there will be a space between the tie and the upper portion of The roller 15 is, moreover, intended to operate in the rear end of the chamber to enage the rail to the body at the rear end of the latter while the arm 6 is juxtaposed with the tie at its lower portion 0 1y. 1

13 represents a tooth depending from the frame 13 and engageable in any 0 the transverse grooves 20 provided in the floor 12 of the body 5 to prevent any accidental rear movement of the frame in the event of the roll becoming tem orarily loose.

The device thus ing engaged at its ends will, upon being subjected to an strains, have a tendency to bend and be l ess liable to break or become displaced when the force is excessive. Because of the converging surfaces of the rail and body against which the roller acts any forward creeping of the rail is obviated the rear. side of a tie.

thereof and the ad-- the arm and the body.

when the anchor is placed against Should the track be utilized for traflic in both directions, then the anchor should be used on both sides of a tie, as would also' be the case on certain inclined ways or grades.

What I claim is-- 1. In a device of the class described, a rail-clamping means comprising a chambered body, said body having at its top a longitudial groove communicating with the referred to chamber and disposed to provide two inwardly directed flanges at opposite sides of the groove whereby the body may be suspended from the flanges of a track rail, and means insertible within the body chamher from one end of the body and below the rail for securing said body to the rail and also serving to hold said body in juxtaposition with a track tie.

2. In a device of the classdescribed, a rail-clamping means comprising a cham- )ered body provided with an arm depending from one end thereof, said body having at its top a longitudinal groove communicating with the referred to chamber and disposed to provide two inwardly directed flanges of unequal widths at opposite sides of the groove whereby the body may, by being tilted, be engaged With-the flanges of atrack-rail, and means insertible within the body chamber and below the rail for securing said body to the rail.

, 3. In a device of the class described, a rail-clamping means comprising a body adapted to be suspended from the flanges of a track-rail and having an arm depending from one end of said body, said body being provided with a recess having a floor inclined from the plane of the underside of.

said rail, and a roller adapted to mutually engage against the underside of said rail and the aforesaid floor to couple said body to the rail and also serve to maintain the body in position to cause the arm thereof to bear against a track tie.

4. In a device of the class described, a rail-clamping means comprising a body adapted to embrace the flanges of atrackrail and having an arm depending from- 5. In a device of the class described, a

one-part body provided with means integral therewith for detachably suspending the same from the flanges of a track-rail, said body being chambered to provide a recess subjacent to said rail flanges and with a floor disposed in angular relation to such flanges, a roller, and means provided with a recess to accommodate said roller and adapted to be inserted therewith in said recess to maintain the axis of the roller in transverse relation to the rail for coupling said body to the rail, said frame also serving to enable the roller to be readily removed from said recess for disengaging said body.
